 This document outlines major changes between releases.
 
-## 0.106.1 "Implication" (3 Jun 2024)
-
-An urgent release that fixes mainnet state difference at block 5462944 which halts
-blocks processing starting from the height 5468658. This release requires full node
-DB resynchronization for mainnet nodes. T5 testnet DB state is not affected by this
-bug (at least up to the current 4087361 height). Thus, DB resynchronisation may be
-skipped for testnet nodes. No configuration changes implied.
-
-Bugs fixed:
- * mainnet state difference at block 5462944 caused by runtime notification
-   permissions check against the updated contract state instead of executing state
-   (#3472)
- * unused neofs-contract dependency in the node modules (#3458)
-
-## 0.106.0 "Zephyranthes" (21 May 2024)
-
-We're rolling out a large set of updates including all of Neo 3.7.4 protocol changes:
-native contracts update functionality and extended native contract APIs united under
-the upcoming Cockatrice hardfork. For smart contract developers an ability to
-generate smart contract bindings with dynamic hash is supported as well as a number
-of useful extensions for `unwrap` package, compatible NNS smart contract RPC binding
-and a lot of other handy enhancements. This release also includes a couple of severe
-regression bug fixes affecting the node state. As a bonus of fixing a wide range of
-failing tests, we've refactored the node services start and shutdown procedures to
-make it more stable. This version drops support for Go 1.19 and requires 1.20+ to
-build (with Go 1.22 supported).
-
-Notice that this release requires full node resynchronization for both mainnet
-and testnet nodes. Please pay a special attention to the Cockatrice hardfork schedule
-and check your configurations. It should be configured for 3967000 of T5 testnet and
-5450000 of mainnet. To ensure compatibility your node must be configured
-appropriately.
-
